You can download USB Webcam support packages for MATLAB, which should let you stream Webcam data right into MATLAB on your PC: http://www.mathworks.com/hardware-support/matlab-webcam.html
As for the robot servos, that depends on how they are controlled. What are the servos connected to -- an Arduino or something?

Perfect!
So, you can look at Image Analyst's color tracking demo and wrap that around the USB Webcam and Arduino support packages for sensor input and actuator output, respectively.
Have fun :)

See my attached demo where I find and track a green Sharpie marker in a video. You'd just pull the frame from your video feed instead of from the video file.

You need to either get the Image Acquisition Toolbox, or use the built-in webcam support: http://www.mathworks.com/support/2014a/matlab/8.3/demos/webcam-support.html
